From what I notice, yeah.
A good majority of people around here in that age group still talk about and occasionally support a lot of their nostalgic favorites, including SpongeBob, although I'm not sure if too many of them still watch it every week. Whenever I mention to my friends that something like Looney Tunes, Dexter's Laboratory or Rugrats is airing again, they try to watch them when they can and enjoy them as much as they did when they were younger. Heck, I was talking to one of my friends about Jonny Quest earlier, and he's bound to watch some of the original episodes again soon.
Then I know a few people who watch newer series like Phineas & Ferb, Young Justice, Adventure Time, and even the new My Little Pony- mostly girls on the last one, but I got some male friends to watch bits of it, and they understand why it has such a strong following out of the demographic.
And of course there are the Disney films, but that's an entirely different conversation I'll have to share with you guys. To cut it short here, just about everyone from where I am is a fairly big fan of the mouse house.
I'm the only one who actively keeps up with the industry among my friends, but when the getting's good, I'll try to sell something to my friends. A lot of people I know are open to new things, even if they're airing on Cartoon Network before [as].
I think my generation, at least this sanction, are a little more open to animation than previous ones is because we just had better shows growing up back then and more ways to access cartoons. I know everyone's childhood is different, but I can't imagine too many teenagers in the 80's going around saying "hey man, new Super Friends is on! We should totally watch it", even if Super Friends was their favorite show growing up in the 70's. True, nostalgia for the 80's was in big demand a few years ago and is still popular today, but that type of childhood yearning is more prevalent during a later part of your life than while you're in high school or college.
The Disney, Nick, Warner and Cartoon Network shows just have aged better in the eyes of our generation, and watching a lot of them now, they seem to hold up fine and contain means of entertainment we didn't notice when we were younger. And since a lot of us grew up on series still airing today or have been recently like SpongeBob or Ed, Edd, n' Eddy, we're likely to stick around to see what's on Nick and Cartoon Network and keep an eye on that as well.
